This invention relates to heating devices.

One of the objects of the invention lies in the provision of a heatingstructure which comprises a radiator surrounded by a housing having aforced draft means therein for projecting a blast of air through theradiator portion into the room or dwelling to be heated, the casingbeing formed, however, to also absorb the heat developed from theradiator, and by means of conduits to conduct same to other portionsofthe dwelling.

Another object lies in the provision of a heater member comprising atubular radiator adapted to be heated by any character of heatingelement, the radiator being surrounded by a housing having a forceddraft mechanism therein for inducing a flow of air through the radiatorinto a room or dwelling to be heated, .the air being heated during itspassage through the radiator.

Still another object lies in the provision of a heater mechanismcomprising a tubular radiator portion, heating mechanism of any kindtherefor, a housing for the radiator having a forced draft meanstherein, said housing being so constructed and arranged as to` induce aflow of air thereinto in a manner to initially preheat same and then bymeans of the forced draft arrangement to project said initiallypreheated air about the tubes of the radiator directly into a room ordwelling to be heated and finally there being provided in connectionwith the housing member a means forabsorbing and conducting.

the remaining heat from the radiator to vother parts of the dwelling.

A further object lies in the provision of a heating member whichcomprises a housing capable of operative arrangement with any characterfof heating mechanism, said housing having a forced, draft member inconnection therewith and so arranged as to induce a ow of air intothehousing andto permit projection of said air through the heating member,thus raising the temperature of the air prior to its projection into theroom or dwelling to be heated.

A'still further object lies in the provision of a housing member havinga forced draft member.

therein, said housing member being adapted to be operatively associatedwith any character of heating element in a manner to project air aboutthe heating device, thus raising the temperature thereof prior to itsprojection into the room or dwelling to be heated, there alsov beingassociated with said housing member a means for absorbing additional.heat from the heating mechanism and conducting same to other portionsof the dwelling.

Yet a further object lies in the provision of a y 1 claim. (ci. 257-137)v portable heating device comprising a housing member including a forceddraft arrangement therein, same being adapted to be associated with anycharacter of heating element in such manner y as to induce a fiow of airinto said heater and to 5 project said air upon being heated by theheating mechanism from said structure directly into a' room or dwellingdesired to be heated. y

An additional object lies in the construction of a portable heating unitcomprising a housing member having a forced draft member therein, saidforced draftmember operating to induce aH flow of cool air into theheater, to initially preheat same and finally to project said initiallypreheated air through or about the heating mech- 15.

anism to which it is attachedl in such manner as to heat in a forcedmanner a room or dwelling to be heated, said housing also being providedwith means for absorbing any remaining heat from the heating mechanismand conducting same to other portions of the room or dwelling to beheated.

Other objects will appear in the following speciiication taken inconnection with the annexed drawings, in which.-

Fig. 1 is a front elevational view of myheating device;

Fig. 2 is a cross-sectional view thereof Fig. 3 is a view showing amodification of the housing member; and

Fig. 4 is another v iew showing a modication of my heating device as aportable unit and in connection with a conventional radiator.

Before referring specifically to the drawings, it might be stated thatthe present application is directed to a type of heating device which isadapted -to be used either in connection with a conventional radiator ofhot water or hot air design, or with any character of heating mechanism,whether it be of the tubular radiator type heated 4 0 by gas,electricity or the like, or Whether it be associated with heatingdevices of otherthan the tubular radiator type.

For simplicity, in the drawings the heating device has been shown atfirst in connection with a simple tubular radiator heated bytheconventional gas jets. However, it is emphatically stated at this timethat the character of radiator and the heating element therefor need notbe necessarily gas but might as well be electricity, oil, coal or thelike.

Referringto the drawings, a housing member is shown comprising an uppercover portion I2,

a lower base member I3, a front portion I4 partially closing the forwardportion of the heater,

said member being supported, as clearly shownin Flgs. 1 and 2 of thedrawings, in an upper and elevated position rearwardly of the uppersection of a tubular hot air radiator portion I9.

The radiator I9, as disclosed, is divided into two sections by means ofthe wall I1. Beneath the radiator I9 are disposed a gas heatingarrangement .20 of conventional construction.

Adjustable louver construction 2I is provided for controlling the amountof air at atmospheric pressure which is delivered to the conventionalgas jet mechanism, the same obviouslybeing necessary for combustionpurposes.--

In Fig. 2 it will be noticed that upon operation of the electric fan theair is drawn into the heater in the direction of the arrows, the samepassing about the lower radiator portion and therefore being initiallyheatedpriorto its exit from the heater through the upper portion of theradiator, as again shown by the direction of the arrow.

In all of the figures with the exception of Fig. 3 it will be found thatforming a Part of the housing is a heat collecting chamber 22, which hasconnected therewith a conductor pipe or ue 23 having disposed therein adraft regulator 24. Such structure is used in connection with thehousing member, and in order to absorb the remaining heat from theradiator and to` conduct same either to a different part of the room tobe heated or to another room of the dwelling to be heated.

, As respects Fig. 3 of the drawings, the fashioning of the gas heateris substantially the same, and for this reason it is not thoughtnecessary to describe same, other than to say that in this instance therear wall I 5 as well as the lower portion of the radiator and housingthereof has been removed, and the fan is disposed in the rear of thecasing in such manneras to force air at atmospheric pressure directlythrough the radiator portion in the direction of the arrows. In thisinstance, also, the front cover 24a merely encloses radiator I9 inasmuchas the lower portion has been removed. Further, the electrically drivenfan member 25,15 supported as at 26 in the rear of the casing in suchmanner as to vin the direction of the arrows, as shown in said figure.

As far as the structural arrangement and disposition of theconventionalgas jet mechanism is concerned, same is shown at 28 and isexactly the same as in the other figures.

As respects the operation, as is apparent from the drawings, the onlydifference lies in the fact that the'air forced about the radiator isnot initially heated. For certain types of dwellings, such a gas heatermay be operated just as efficiently as in the first describedconstruction.

In Fig. 4 of the drawings, a housing member 29 is found correspondingexactly to the housing mechanism shown in Figs. 1 and 2 of the drawingsand'bearing the same numerals, with the exception that in this instancethe housing is formed as a -portable unit and is placed about aconventional radiator which may be either of the hot air or hot watertype.

Inasmuch as the operation of such unit is exactly the same as that shownin Figs. 1 and 2, the operation of the units shown in Figs. 1 and 2 andthat shown in Fig. 4 will be described as one.

Whether the heating unit be formed as a stationarymember in connectionwith a fixed radiator portion, or whether it is formed as a portableunit and associated with any character of radiator or any other kind ofheating device, as far as theoperation thereof is concerned. the coolair, bymeans of the forced draft member, namely, the fan, is inducedinto the housing at the lower portion, said air being initiallypreheated and finally forced by means of the fan `ro0m or to other roomsin the dwelling. It might' be stated at this time that it` is immaterialwhether the fan or forced draft member is disposed in the upper or lowerpart of the radiator or whether the air initially induced into thehousving is taken in at the lower part or at the upper part, this beingmerely a matter of construction.

Similarly., with respect to the operation of the device when formed as aportable unit, the only difference is that the structure itself iseither placed about a conventional radiator or is placed over and inconnection with some heating unit, either electric, gas, oil or coal, inwhich instance likewise the fan induces a iiow of air into the unit,finally projecting the heated air directly into the room to be heated,the remaining heat being absorbed and re-conducted by the upper portionof the housing as heretofore described.

Further, as respects the operation of applicants heating structure, itmay be stated that adjustment of the amount of heat given off therefrommay be controlled either by varying the opening j through which the heatis projected by means of louver mechanism or the like, or varying theopening in the rear ofthe forced draft member in any well known manner.As far as the amount of heat delivered to the radiator, or as a matterof fact, any heating unit desired is concerned,

this of course is so conventional as to require no f description, but itis apparent that the degree of heat delivered to the radiator may bemainf tained in a uniform manner as well as being adjustable by wellknown means.

What I claim is:

A heater comprising a portable housing member entirely closed upon threesides, mechanism for with which the portable housing is associated andmeans to conduct the same to any desired point.
